Abstract: Disclosed is a process for purifying a high temperature reducing gas by removing sulfur compounds contained in the reducing gases by dry adsorption on an adsorbent.  The process comprises subjecting the high temperature reducing gas to a catalytic CO-shift reaction in a reactor having a catalyst and equipped with a heat recovery means for controlling the reaction gas temperature while injecting steam into the high temperature reducing gas, in order to convert the content of CO in the high temperature reducing gas into CO2, effecting the removal of the sulfur compounds and CO2 by dry adsorption  on  adsorbent under control of the temperature of the gas by means of the heat recovery means of the reactor and separating the sulfur compounds from CO2.  The sulfur compounds separated from CO2 may be supplied to a Claus process sulfur recovery unit to convert H2S in the sulfur compounds into elementary sulfur to recover it.  Also disclosed is an integrated coal gasification combined cycle (IGCC) power plant, which comprises a CO-shift reactor for converting CO in a purified product gas into CO2 disposed between a gas purifier and a combustor of a gas turbine power generation unit, a means for removing CO2 and sulfur compounds from the coal gas in dry system and a sulfur compound separator for separating sulfur compounds from the gas left after the removal of CO2 and sulfur compounds.

Abstract: A dark current correction apparatus eliminates a dark current signal component or components from an output signal of an imaging device having an array of pixels. The apparatus includes an A/D converter for digitizing the output signal, and a memory for storing level data of the digitized signal while exposure of the imaging device is controlled to be at a zero level or a uniformly illuminated level, according to whether dark current correction or white current correction, respectively, is to be performed. A dark current correction signal former generates a dark current correction signal or signals from data read out from the memory. The dark current correction signal or signals are applied to a correction circuit which processes an output signal produced by the imaging device during normal imaging operation in accordance with the correction signal or signals in order to eliminate the dark current signal component or components from that output signal.

Title: Electro/hydraulic variable valve timing system
Inventor: FEULING JAMES J
IPC: F02D13/02
Filed: 1991-10-01
Abstract: ABSTRACT OF THE DISCLOSURE      In an internal combustion engine utilizing hydraulic valve lifters, a source of pressurized oil at a higher than normally expected pressure is supplied thereto.  The source utilizes the engine lubricating oil from the engine sump or crank case and the spent oil from the hydraulic lifters is returned to the engine crank case.  The oil delivered to the lifter galley is derived from either an engine oil pump which produces a higher pressure oil flow then conventionally desired for normal engine operation, a separate or oil pump oil pumps especially for the valve galley.          The pressure setting of the oil output from either pump is determined by the engine RPM, ie. higher pressure with higher engine RPM or from pump speed if an electricly operated separate pump is employed.  The exact oil pressure level delivered to the valve galley or to individual valve galleys is determined by an on board computer (engine controller) monitoring the manifold pressure, engine RPM and throttle position so that the hydraulic lifter plunger is always in contact with the valve stem regardless of engine RPM or pump motor speed and variable and different amounts oil pressure and resulting valve lift can be achieved at various selected locations on the valve lift curve created by the valve's camshaft lobe.  Variable high oil pressure is supplied only to the lifters to selectively alter their normal degree of valve lift at any location along the valve's cam operating curve while the remaining oil delivery areas of the engine operate at their conventional or normally expected oil pressure levels.  In event of a failure of normal engine oil pump operation when a second auxiliary pump for galley delivery is used, an electric value is provided to channel oil from the auxiliary pump to the engine areas requiring lubrication.

Filed: 1992-05-21
Abstract: A remotely retunable receiver for use in a satellite video programming distribution system includes the capability to retune groups of subscribers to different satellite feeds during a blackout of a video programming event, To achieve flexible control over program blackouts, a receiver retune command message is selectively sent to desired groups of descramblers at CATV satellite downlinks. The retune command message identifies an alternate satellite feed and a time for which the satellite receiver is to tune to the alternate satellite feed. The receiver stores the retune command, and at the appropriate time retunes the satellite receiver to the identified alternate feed, By command massages received on the alternate feed, the group of blacked out satellite receivers are returned to the original programming channel at the end of the blacked out event. Also provided is a command message for local insertion of demographically targeted advertising which command message designates the start tine and duration of the local insertion. Furthermore, a home channel command is provided to individual satellite receivers to return the receiver to a home satellite feed in the invent of an unrecoverable error.

Inventor: KONDOU SEIJI
IPC: G06F1/24
Filed: 1992-07-24
Abstract: A multi-processor circuit having a plurality of microprocessors coupled to a shared circuit includes an OR Gate for receiving read signals from each of the microprocessors, and a D-type flip flop which toggles an initial processing permission signal between a permission state and an inhibit state. When power is initially supplied to the circuit, or upon receipt of a reset signal, the initial processing permission signal is set by the D-type flip flop to the permission state. In this condition, the first microprocessor to recognise the permission state of the initial processing permission signal issues a "read" signal and performs an initial processing operation. In response to the "read" signal, the OR gate transmits a trigger signal to the D-type flip flop to toggle the initial processing permission signal to the inhibit state, thereby preventing the other microprocessors from performing the initial processing operation. When all of the microprocessors are operating normally, the initial processing operation is ordinarily carried out for the shared circuit by the first microprocessor to generate a read signal. When a failure occurs in one of the microprocessors, the initial processing can is accomplished by another microprocessor to start the operation of the multi-processor system. Consequently, an initial processing operation for the shared circuit can be reliably performed even if one of the microprocessors is operating abnormally.
